White multibeam antennas and equipment mounted on the catwalk, in the steel structure of the roof ring, next to the floodlights — The arena covered from two positions: one 12-port multibeam antenna (1695-2690 MHz) at each end stand, fed through 12 feeders of 7/8".

The corner of the roof ring seen from the stands, with the equipment mounted under the steel structure — The 5G extension: one AAU5614 active antenna 300 mm from the existing antenna, on a galvanized bracket designed by Claritech, with 2 optical fibers and a -48 VDC cable pulled over 80 m of existing routes.

In brief

At a first-league stadium in Bucharest, Claritech extended the existing radio system of one of the leading mobile network operators with 5G, without touching the RF installation in service. The existing coverage is provided by 2 multibeam antennas with 12 ports each in the 1695-2690 MHz band, one at each end stand, each fed through 12 feeders of 7/8”. The extension added one AAU5614 5G active antenna 300 mm from each existing antenna, on 24.32 kg galvanized brackets designed in-house and verified for wind, snow and seismic loads. For each active antenna, 2 optical fibers and a DC power cable were pulled over 80 m of existing routes, and two 12U racks with -48 VDC power were added in the technical rooms. The extension was executed on the live system, with no changes to the existing RF installation and no new feeders.
